My research is currently focused on three broad topics. First, I am investigating the role of wildland fire in acting as a fuel treatment. That is, I am quantifying how past wildland fire affects subsequent fire spread, severity, size, etc. Second, I am conducting studies that identify the relationship between climate and fire regimes. One of the primary goals of this research is to better understand how climate change will affect fire regime characteristics. Third, I am identifying factors that are likely to result in fire-facilitated conversion from forest to non-forest. Many, but certainly not all, of my studies are conducted using data from designated wilderness or other protested areas (e.g., National Parks). The relevancy of my research, however, is applicable across all land designations.
I am interested in spatial interactions between past wildland fire and subsequent fire events. I am specifically interested in how past fires “regulate” subsequent fires in terms of fire size, severity, ignition potential, etc. I am also keenly interested in better understanding how climate shapes fire regimes, which is particularly relevant given that climate change will inevitably result in changes to fire regimes. Furthermore, I am interested in identifying those factors that control conifer seedling establishment and survival (i.e., regeneration). Other research interests include satellite detection of fire effects and spread, retrospective evaluations of the influence of weather and topography on fire behavior, and the restoration of fire as a natural process. Designated wilderness and similarly protected areas are excellent “laboratories” for conducting much of this work because there is minimal human infrastructure (e.g., roads) and, in several protected areas, many fires are not actively suppressed. I also have non-fire research interests, primarily involving the field of “landscape genetics”, which uses genetic data to identify landscape features (e.g., topography, vegetation) that inhibit or facilitate movement (or connectivity) between individuals/populations of flora and fauna.
- Exploiting remotely sensed data to better understand fire behavior and effects: I took the lead in developing a 1) method for fine-resolution mapping of fire progression, or day of burning, using very coarse satellite (MODIS) fire detection data and 2) new burn severity metric using Landsat imagery called the relativized burn ratio (RBR).
- Corridor/connectivity modelling: I contributed to several projects modelling the connectivity of wolverine, lynx, and mountain beaver.
- Evaluating approaches for mapping burn probabilities for a quantitative risk analysis framework: I contributed to several projects that involved the use of fire simulation models to map the probability of burning in several large protected areas.
- Biogeography, island biogeography, and extinctions in protected areas: In a past life, I was involved with several research projects that evaluated 1) factors responsible for primate species distributions and 2) extinctions within protected areas.
Why This Research is Important
Wildland fire is one of the most pervasive and important ecological processes on the planet, and although the Forest Service spends in excess of one billion dollars per year suppressing fire, large areas of land burn each year. Consequently, there is a growing recognition that our society needs to better co-exist with wildland fire and that it should be restored as an ecological process to some landscapes. How to best restore fire, however, is challenging because of excessive fuel buildup, risks to lives and property, and climate change. Designated wilderness and similarly protected lands turn out to be excellent “laboratories” for conducting studies on how fire naturally responds to climate, topography, weather, fuels, and past fires. As such, studies conducted in protected areas can provide information to managers, policy makers, the public, and other scientists that will better enable the restoration of fire as a natural process in a safe and effective manner.
